Hi built a Rat clone (fuzzdog rodent pcb) with a sister board including differents clipping options.
When i compare with my procorat2 china from 2010s, sound and pedal behaviour are prety close but i'am a bit dispointed because i get less mid frequencies on the clone (around 800hz-1000hz) than on the chinese one. Its subtile but the sound is less shining, more digged in the mid and less beautifull.
- all components value are identic but the IC: the clone has a lm308 Nos chip, the chinese has the op07cp.
- i tried different filter caps (2n2 2n7 3n3...,) the problem is not here.
- to do test I shorted the ruetz mode, and i shorted the clipping board back to the 2x1n4148 originals diode.
Some people saying there is no audible difference between the 2 IC, some other affirm the op07 sounds more mid.
On the other hand some people saying chinese Rat 2 sounds more mid than classic one .
In the doubt i ordered an op07cp for testing...
Any experiences are welcome many thanks
